Since 2003, a LHC dipole magnet turned into a telescope has been following the Sun's movements from behind a concrete wall. This is the CAST experiment - hunting for hypothetical "axion" particles that could be produced in the centre of our star ☀️ Find out more about this experiment: https://home.cern/science/experiments/cast | CERN

🕶 Discover CERN in Virtual Reality with this short clip. The Large Hadron Collider (LHC) consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. The Compact Muon Solenoid (CMS) is a general-purpose detector at the LHC. It has a broad physics programme ranging from studying the Standard Model (including the Higgs boson) to searching for extra dimensions and particles that could make up dark matter. Al
